Insights from coproduced scenarios toward urban sustainability transformations

Urban sustainability transformations call for fundamental shifts in how cities are organized, developed, and governed. Yet we need a better understanding of the diversity of visions and pathways that can enable transformative change. We address this gap through an analysis of 60...

Seasonal surface melt onset and firn freeze-up across the central Wrangell and St. Elias Mountains

Abstract. High-elevation alpine firn is increasingly influenced by surface melt and meltwater retention, yet the spatial extent and timing of these processes remain poorly quantified. Here we present spatially distributed estimates of seasonal surface melt onset and firn freeze-u...

A Remotely Delivered Exercise-Based Rehabilitation Program for Patients with Persistent Chemotherapy-Induced Peripheral Neuropathy (EX-CIPN): A Phase I Feasibility Trial

Background: Chemotherapy-induced peripheral neuropathy (CIPN) affects two-thirds of patients who receive neurotoxic chemotherapy. In almost half of these patients, CIPN is persistent, with limited treatment options. Exercise-based rehabilitation shows promising results in improvi...

Low-cost geometry-tunable PDMS intraocular lenses fabricated using LCD 3D-printed molds for canine ophthalmic applications

This study demonstrates the feasibility of fabricating geometry-tunable polydimethylsiloxane (PDMS) intraocular lens (IOL) prototypes using consumer-grade liquid crystal display (LCD) 3D-printed molds and PDMS casting. A reusable mold fabrication strategy incorporating a PMMA bar...

Cosmological Constraints from Full-scale Clustering and Galaxy–Galaxy Lensing with DESI DR1

Abstract We present constraints on cosmic structure growth from the analysis of galaxy clustering and galaxy–galaxy lensing with galaxies from the Dark Energy Spectroscopic Instrument (DESI) Data Release 1. Our analysis includes four samples drawn from the Bright Galaxy Survey (B...

Shoaling of internal solitary waves over linear slopes with variable topography

This study investigates the influence of variable topography on the kinematics of internal solitary wave shoaling across various breaking regimes under the unifying condition of a slope-intersecting pycnocline. It is demonstrated that bottom corrugations can significantly modify...

A critical comparative policy analysis: Older worker retention in Canada and Sweden

Abstract Population ageing across OECD countries has cultivated an interest in policies to extend working life. However, the ability to extend working life is unequal between job sectors, with older workers engaged in physically demanding work already experiencing challenges to w...

Photon Absorption Remote Sensing Virtual Histopathology: A Preliminary Exploration of Diagnostic Equivalence to Gold-Standard H&E Staining in Skin Cancer Excisional Biopsies

Background: Photon Absorption Remote Sensing (PARS) enables label-free imaging of subcellular morphology by observing absorption interactions. Coupled with deep-learning, PARS produces label-free virtual hematoxylin and eosin (H&E) images in unprocessed tissues. This study evalua...

Joint Modeling of GD-1 and C-19 as Old Streams

Abstract DESI observational data for the GD-1 and C-19 streams are compared to stream simulations in an evolving multihalo potential of a Milky Way–like galaxy based on a cosmological Milky Way–like simulation. The number of subhalos decreases with time, and the subhalo-stream en...

The overlooked role of food and cultural dimensions in recreational fisheries

Our study examines the diversity of values within a superficially homogeneous recreational fishery and its relationship to angler diversity. We collected data on fishing preferences, behaviors, catch usage, and sociodemographics from 443 shore anglers across 10 cities in the lowe...

Multivalued forbidden numbers of two-rowed configurations -- the missing cases

The present paper considers extremal combinatorics questions in the language of matrices. An $s$-matrix is a matrix with entries in $\{0,1,\ldots, s-1\}$. An $s$-matrix is simple if it has no repeated columns. A matrix $F$ is a configuration in a matrix $A$, denoted $F\prec A$, i...

Technical note: How well do evapotranspiration partitioning approaches perform in moss-covered wetlands?

Abstract. Evapotranspiration (ET) is the dominant hydrologic flux in wetlands, and partitioning into transpiration (T) and evaporation (E) is essential for understanding water and carbon dynamics, guiding sustainable water management practices, and predicting responses to climate...

Arm-Strengthening Intervention Program During Radiation Treatment in Breast Cancer: A Prospective Cohort Study

Introduction: Radiation therapy is a critical component of breast cancer treatment; however, it is frequently accompanied by a decline in shoulder strength and function that can impair daily activities and limit long-term recovery. Although exercise can improve physical function...

Enhanced measurements on quantum computers via the simultaneous probing of non-commuting Pauli operators

Measuring the state of quantum computers is a highly non-trivial task, with implications for virtually all quantum algorithms. A promising avenue is multi-copy schemes, where identical copies of a quantum state are measured jointly so that all Pauli operators within the considere...

Targeted genome recovery of under-sequenced microbes from the Sequence Read Archive STAT

Most microbial species are represented by a single genome in public databases. The lack of genomes for these ‘singleton’ organisms limits our understanding of their pan-genome diversity and evolution. Although the Sequence Read Archive (SRA) contains millions of sequencing datase...

Swiping into risk and reward: dating apps, digital leisure, and feminism in the uneven terrain of technological intimacy

Dating apps have become central to contemporary digital leisure, functioning as immersive environments where intimacy, pleasure, and safety are negotiated across digital and embodied contexts. Drawing on feminist theory, post-humanist perspectives, and narrative inquiry, this stu...

Awareness and Use of Delta-8-THC Cannabis Products in the United States: Findings from National Surveys in 2021 and 2022

Introduction: While recreational marijuana remains illegal under federal law in the United States, “hemp-derived” products that contain less than ≤ 0.3% Delta-9-tetrahydrocannabinol (THC) were legalized in 2018. New classes of intoxicating products have proliferated, such as Delt...

The Composite Spectrum of QSO Absorption Line Systems in DESI DR2

Abstract We present details regarding a composite spectrum of quasar (QSO) absorption line systems. In this composite spectrum, we identify more than 70 absorption lines and observe oxygen and hydrogen emission features at a higher signal-to-noise ratio than any previous study. A...

Elucidating the impact of plants in recruitment of rhizosphere microbiome for enhancing pathogenic resistance, stress resilience and crop productivity

Plants, despite their immobile nature, demonstrate an incredible array of adaptive strategies, which position them as opportunistic organisms in their dynamic interactions with the microbial world. Microbial communities have been integral to plant evolution, helping early land pl...

Revisiting the relation between oral contraceptive use and attentional engagement in everyday life: The role of formulation

Oral contraceptives (OCs) are composed of artificial estrogen (ethinyl-estradiol) and/or progesterone (progestin), which can attach to receptors in the brain and potentially influence cognition. One prior study suggested that OC use was associated with increased mind-wandering –...
